混合燃料装填状态及结构特征分析

Comparative Study of the Loading State and Structure for the Mixed Fuel

FAE战斗部要适应一定的使用温度范围 ,壳体内装填的混合燃料体积会随着温度的变化发生变化 ,需要在战斗部内留有一定空间间隙 ,间隙大小需要综合考虑燃料的温度系数、战斗部壳体强度及战斗部质量偏心等因素。本文推导出能够满足战斗部安全要求和发射精度要求的壳体内预留间隙计算方法。

The warhead of FAE is needed to have certain operational temperature range. The volume of the mixed fuel in the shell will be changed along with the environmental temperature. So there must be a pre reserved space in the warhead case. The dimension of the space is determined by several complications, such as the temperature coefficient of the mixed fuel, the intensity of the shell and the mass eccentricity of the warhead. In this paper, the method to calculate the pre reserved space in the shell is carried out, which satisfies both the safety of the warhead and the launching precision.
